Quasinormal Ringdown and Echoes in Accreting Exotic Compact Objects
Chanchal Sharma, Kabir Chakravarti, Sudipta Sarkar
Exotic compact objects (ECOs) may produce late-time gravitational-wave (GW) echoes, but sufficiently compact ECOs undergoing realistic accretion may eventually form an event horizo…
Ladder Symmetry: The Necessary and Sufficient Condition for Vanishing Love Numbers
Chanchal Sharma, Shuvayu Roy, Sudipta Sarkar
Black holes in four-dimensional, asymptotically flat general relativity have vanishing static tidal Love numbers (TLNs), a property tied to a hidden symmetry of the perturbation eq…
Exploring Ladder Symmetry and Love Numbers for Static and Rotating Black Holes
Chanchal Sharma, Rajes Ghosh, Sudipta Sarkar
Black hole solutions of general relativity exhibit a symmetry for the static perturbations around these spacetimes, known as "ladder symmetry". This symmetry proves useful in const…
